    • FEM Convergence for PDEs with Point Sources in 2-D and 3-D 

      Gobbert, M.; Kalayeh, K. M.; Graf, J. S. (2015)
      Numerical theory provides the basis for quantification of the accuracy and reliability of a FEM solution by error estimates on the FEM error vs. the mesh spacing of the FEM mesh. This paper presents techniques needed in ...
